Flexible Sigmoidoscopy
Examining the Lower Colon
Are you experiencing rectal bleeding, persistent diarrhea, or changes in bowel habits? Flexible sigmoidoscopy allows Dr. Tieng to examine the rectum and lower portion of the colon to identify inflammation, bleeding, polyps, and other abnormalities.
Flexible sigmoidoscopy uses a thin, flexible camera to examine the rectum and lower colon. Unlike a colonoscopy, which examines the entire colon, flexible sigmoidoscopy focuses only on the lower portion of the digestive tract.
The procedure may be recommended to evaluate:
- Rectal bleeding
- Persistent diarrhea
- Changes in bowel habits
- Lower abdominal discomfort
- Inflammation of the rectum or lower colon
- Abnormal imaging or previous test results
- Ulcerative colitis or other inflammatory conditions
Sedation is generally not required because the procedure is brief and examines only the lower colon. However, recommendations may vary depending on your medical needs and the circumstances of the examination.
Preparation is usually simpler than preparation for a full colonoscopy. You may be instructed to follow a limited diet, use one or more enemas, or take another bowel-cleansing preparation before the procedure.
The office will provide specific instructions based on your appointment time and medical history. Following these instructions carefully helps ensure that Dr. Tieng can clearly examine the lower colon.
The examination itself typically takes approximately 10 to 20 minutes, although you should allow additional time for check-in, preparation, and discharge.
Most patients can leave shortly after the procedure and resume normal activities the same day, particularly when sedation is not used. Temporary gas, bloating, mild cramping, or a small amount of rectal bleeding may occur.
You will receive instructions explaining when to resume your usual diet and activities, as well as symptoms that should prompt a call to the office.
Dr. Tieng can usually discuss the initial findings immediately after the examination. If tissue samples are collected, laboratory results may take several days, and the office will explain how you will receive the final results.
